Terpene resin is polymerized from turpentine. It is an excellent non-toxic and odorless tackifier with strong adhesion, heat resistance, radiation resistance, acid and alkali resistance, aging resistance and excellent dielectric properties. , can significantly improve the initial viscosity of pressure-sensitive adhesive products. And can be well compatible and dissolved in rubber, adhesives, hot melt coatings, paints, high-end printing inks, fillers, anti-rust paint and chewing gum and other products.
Physical and chemical properties
Terpene resins are yellow transparent, brittle thermoplastic solids. It has the properties of non-toxic, odorless, radiation resistance and anti-crystallization; it is relatively stable to oxygen, heat and light; it has good compatibility with various synthetic substances; good heat resistance, dilute acid and dilute alkali resistance; strong viscosity , Strong electrical insulation; easily soluble in aromatic hydrocarbons and vegetable oils, insoluble in water and ethanol.
The main purpose
Terpene resin is an excellent tackifier of a new star, and its tackifying performance is better than that of rosin, rosin modification and petroleum resin; it is also a modifier of hot melt materials. It has a wide range of applications and is widely used in rubber, adhesives, pressure-sensitive adhesive tapes, hot melt coatings, paints, advanced inks, packaging, anti-rust oils, chewing gum and other industries.
Terpene resin (C15H16) n, also known as polyterpene or pinene resin. It is mainly a series of linear polymers from liquid to solid obtained by cationic polymerization of α-pinene or β-pinene of turpentine under the action of Freight-Kelstein catalyst.
